That thing we cooked up with kiss_me_cassie in the Summer post:

Posing as an upper class American couple, in a sailing vacation in Ibiza. Or Capri. Or somewhere else where Natasha will have the chance to wear the huge sunhat and Clint will be utterly miserable dressed in mariniere shirts.

And after the mission is done, they just take the yacht and disappear for a week of R&R and Fury almost has an aneurysm because this fucking thing costs a fortune, Barton. - "I know sir, she handled like a dream." :D
